Design and fabrication of nanofibrous scaffolds should mimic the native extracellular matrix. This study is aimed at investigating electrospinning of polycaprolactone (PCL) blended with chitosan‐gelatin complex. The morphologies were observed from scanning electron microscope. As‐spun blended mats had thinner fibers t…
Dual emulsion electrospinning is introduced to form core–shell nanofiber coatings with the self-healing agent dimethyl siloxane (DMS) and dimethyl-methyl hydrogen-siloxane (cure) separately in the cores. The coating pores are also intercalated by polymerized (cured) poly(dimethyl siloxane) (PDMS) resin as an outer mat…
Organic–inorganic hybrid heterogeneous nanocatalysts were successfully fabricated via covalent anchoring of cobalt(II) or copper(II) acetylacetonate complexes ([Co(acac)2] or [Cu(acac)2]) onto core–shell structured Fe3O4@SiO2 previously functionalized with 3-aminopropyltriethoxysilane (APTES). Surface functionalized n…
Carbazole and triphenylamine-substituted ethenes with AIE characteristics, mechanochromic fluorescence properties and strong blue EL are synthesized.
A facile, economic and environmentally friendly one-step approach for the preparation of highly luminescent graphene quantum dots (GQDs) was developed using a hydrothermal reaction between citric acid and urea.
Current study reported a facile method to investigate the effects of stacking sequence layers of hybrid composite materials on ballistic energy absorption by running the ballistic test at the high velocity ballistic impact conditions. The velocity and absorbed energy were accordingly calculated as well. The specimens…
Cellulose was extracted from durian rind using delignification with acidic sodium chlorite then followed by mercerization with 17.5% (w/v) sodium hydroxide. Gas pycnometer indicated that density of extracted cellulose was 1.59 g/cm3. Fourier transform infrared (FTIR) confirmed the removal of non-cellulosic components.…
Recent studies have pointed out the importance of polyelectrolyte assembly in the elaboration of innovative nanomaterials. Beyond their structures, many important questions on the thermodynamics of association remain unanswered. Here, we investigate the complexation between poly(diallyldimethylammonium chloride) (PDAD…
A facile <italic>in situ</italic> procedure has been successfully applied for synthesis of a RGO/Cu nanocomposite, which leads to the highest catalytic activity of Cu nanocatalysts up to now for the dehydrogenation of ammonia borane.
= 0.81), exhibits predominate photocytotoxicity over dark cytotoxicity in LLC cells (lung cancer cells) upon irradiation, making it potentially suitable for use in in vivo photodynamic therapy (PDT). Our results are useful for preparation of transition metal complexes that show strong absorption of visible light in th…
Self-sorting in low molecular weight hydrogels can be achieved using a pH triggered approach. We show here that this method can be used to prepare gels with different types of mechanical properties. Cooperative, disruptive or orthogonal assembled systems can be produced. Gels with interesting behaviour can be also pre…
Among the bio-based polymers developed so far, PLA polymers and their derivatives stand at the forefront of practical use and are currently manufactured. PLLA obtained from naturally occurring l-lactic acid is generally produced and utilized on an industrial scale. Two synthetic routes to PLLA have been known: one is…
The simultaneous ordering of different degrees of freedom in complex materials undergoing spontaneous symmetry-breaking transitions often involves intricate couplings that have remained elusive in phenomena as wide ranging as stripe formation(1), unconventional superconductivity(1-7) or colossal magnetoresistance(1,8)…
The energy density of a hybrid supercapacitor having CoS <sub>2</sub> against activated carbon was increased by direct lithiation of metal sulfide before capacitor fabrication. Lithiation augmented the energy density by two-fold at all current rates and also is responsible for maintaining the capacitance retention dur…
This work reports enhanced thermoelectric properties of transparent thin films. The influence of the composition, thickness and deposition method has been studied, reaching a <italic>ZT</italic> > 0.1 at room temperature.
A multifunctional pH-sensitive polymeric nanoparticle system was developed for simultaneous tumor magnetic resonance imaging (MRI) and therapy. The nanoparticles were self-assembled using the multi-block polymer poly(lactic acid)-poly(ethylene glycol)-poly(l-lysine)-diethylenetriamine pentaacetic acid (PLA-PEG-PLL-DTP…
This tutorial review focuses on the application of mesoporous silica materials, primarily MCM-41 and SBA-15, for the removal of organic pollutants in the vapour phase. After briefly providing an introduction into the types of mesosilica covered in this review article the information is presented on a topic by topic ba…
Addition of filler to polylactic acid (PLA) may affect its crystallization behavior and mechanical properties. The effects of talc and hydroxyapatite (HA) on the thermal and mechanical properties of two types of PLA (one amorphous and one semicrystalline) have been investigated. The composites were prepared by melt bl…
Hydrogen embrittlement (HE) of steels is extremely interesting topic in many industrial applications, while a predictive physical model still does not exist. A number of studies carried out in the world are unambiguous confirmation of that statement. Bearing in mind multiple effects of hydrogen in certain metals, the…
Round the globe, scientific communities have been searching for new materials for “green” energy, producing efficiently both high power as well as high energy density.
